Some people probably know Fisher as Kissimmee's parks and recreation director and O'Brien as a radio personality on WJMK, Magic 1220-AM.

What they probably didn't know that these guys are brothers.

The brothers will team up for the second year in a row to broadcast Osceola County high school football.

The station also broadcasts the University of Florida and Miami Dolphins' games.

''It has been exciting,'' said O'Brien, 35, an employee with the Orlando Post Office. ''It was mixed emotions for both of us. We really didn't know what to expect at first. But once we got rolling, it was the easiest thing in the world to do.''

In case you were wondering, Fisher and O'Brien do not have different parents. Dave O'Brien is his radio name. The change occurred when he was working for a station in Odessa, Texas.

''A guy told me that DJs don't always use their last name,'' O'Brien said. ''He said Fisher didn't sound fluid enough so we decided on O'Brien and it has been that way ever since.''

O'Brien has been in radio for 13 years. However, Fisher, 37, still is earning his wings. In fact, he was reluctant to give it a try until his wife's encouragement helped him make up his mind.

''I wasn't sure it would be a good idea,'' Fisher said. ''But my wife said I sit at home calling the games on television so I might as well do it. I'm glad I made the choice I did. We have been apart for good part of our lives, so its a chance to get reacquainted with him.''

When O'Brien was asked to do the high school football, Fisher was the only choice as his partner.

O'Brien thought Fisher's knowledge of the game would make him a natural for the position.

''I knew that Randy loved the game, was sports-oriented and understood the technical aspects of the game,'' O'Brien said. ''In radio, you have to paint a picture to the fans. I could never do it without Randy's help.''

After last season, O'Brien had severed ties with WJMK. But new mangement, headed by general manager Charley Fowler, persuaded him to come back.

O'Brien has noticed a big difference.

''Fowler and Gus Collie, who owns the station, have worked wonders turning station around,'' O'Brien said. ''They are committed to having an 'honesty is the best policy' type operation. I think that will translate into better coverage.''

Fisher and O'Brien will broadcast 11 games, including last Thursday's jamboree. They will select the best possible high school game of each week.

They also will have the ''Coaches Corner,'' a 25-minute segment in which the broadcasters will go one-on-one with Osceola, St. Cloud and Gateway high school coaches on the upcoming games and current issues. The show will be informative, but not controversial.

''Our goal is to promote Osceola County football,'' O'Brien said. ''We're pulling for all three teams. The toughest thing will be the games they play against each other.''

Fisher: ''The broadcasts will be improved this year because we are better prepared for what we have to do. We want to try to keep things straight during the games.''

The games have been well received by the county, O'Brien said. The broadcasts were so popular last year that some Orlando stations have begun to follow WJMK's lead.

Both men are stunned by the growth of the games' popularity on the radio, but agree it is the most reasonable way to get the games to the people.

''Because of time and cost factors, there aren't always opportunities to see live games,'' O'Brien said. ''But you always have radio.''

Fisher and O'Brien continue to learn about each other as colleagues, brothers and friends. It's that type understanding they want to convey to the radio audience.

They have received many compliments but their father's comment was the most memorable.

''We did a game last season that was extremely long,'' O'Brien said. ''Afterwards, our father said, 'I knew you guys were a big bag of wind, but I didn't know how much until you were on the air for five hours.' ''
